Gemäß einer besonderen Ausführungsform der Erfindung sind die Buchsenkragen von Schlauchanschlussbuchsen nicht wie beim Stand der Technik mit einem mehreckigen, zum Beispiel sechseckigen, Außenumfang versehen, sondern mit einem kreisrunden Außenumfang. Dadurch sind kleinere Abstände zwischen den Flanschlöchern und damit auch zwischen den Schläuchen möglich. Die kreisrunde Form der Buchsenkragen erleichtert den Einbau und den Ausbau der Schläuche, da die radial überstehenden Buchsenkragen in jeder beliebigen Drehrichtung positionierbar sind, ohne mit benachbarten Buchsenkragen zu kollidieren. Dadurch ist auch die Verwendung von größeren Maßtoleranzen möglich. 79According to a particular embodiment of the invention, the socket collars of hose connection sockets are not provided, as in the prior art, with a polygonal, for example hexagonal, outer circumference, but with a circular outer circumference. As a result, smaller distances between the flange holes and thus between the hoses are possible. The circular shape of the bush collar facilitates the installation and removal of the hoses, as the radially protruding bush collar can be positioned in any direction without colliding with adjacent socket collar. This also allows the use of larger dimensional tolerances. 79
